AUTOMOBILE-BUMPER.

Application ni'ea January 31,1917. Serial No. 145,836.

' To" all whom it may concern:

Be it known that I, EDWARD PAimADnn, a

cago; in the county of Cook and State of Illinois, have invented certain new and use ful Improvements in Automobile-Bumpers,

of "which the following is a specification.

My invention relates to automobile bumpers, and has for its general 'ObJGCtS to provide a bumper of adequate strength to.

withstand? severe shocks without damage to the car or to itself; of ample resiliency to absorb shocks With comrrlnnication of only minimal strain or jarto the car and consement of parts; of attractiyeappearance; and of structure. easily appl ed to', and reachly adjusted to fit automobiles of many different makes.

The features of construction and correlation of parts constituting my present invention as pointed out in the appended claims 26 and set forth in the specification, may find one appropriate embodiment in the construction specifically shown in the drawings, whereinp Figure 1 is a perspective View of the bumper applied to the front end of a notor car frame. 7

ning rearw-ardly to the frame A of the car,

and attaehingtmeans 12 to connect the arms to the framel v The bar '10, as shown herein, comprises two spring-steel leaves 13 and 1? rather deep and thin, arranged edge-down, spaced 'one behind the other in approximate parallelism, and =-connected together solidly at both ends and at one or mnreinterrnediate points, through spacing blocks so'that'in plan the bar,-that is straight acro$ its center spanand curving 'rearwardly at i ends in usual shape-forms 'a pluraifiy of cells or chambers, open at tofl tnfi-hottom,

The intermediate space, 21, (a single central one beingshow more may be used) is a ve'rtic y blockfitted between the leaves and by athrough bolt '2 2.ff Thisflcellil of bar I find to be most advantage to even a rather 1i ht pressure without a terially afl'ccting t 6 other leaf, and reason of the solid connection between fth'e leaves,.any larger distortion. of either, leaf can be secured only by an accommodating minor distortion of the other leaf,-

.that'fifi" shocks are materially absorbed within the i structure of the bar itself in the expenditure 1 of force to distort one leaf from parallelism with the other. Y

'Bhe full benefit "of this construction ,is secured by mounting the baron the supports 11 at points local to one bar-lenient 1n the resilient spans of said leaf between t-ipacers and the -arm'supports themselves preferably may be made resilient. i

' Specifically, therefore, the supports 11 are preferably made of spring steeheach of the same depth as thfilbttldfiflNBS and of appro-' priate thickness, each bent as at 23 on a i spring curve from a leg 24 extending straight rearwardly to a foot 25 paralleling the bumper bar, and each foot secured directly to the rear leaf of. the bar at a point intermediate two spacers. Ai clamp 26 comprising two U-holts 27, each embracing; the har-ieaf and the foot, and-ellipses, ing through a bottom plate 28, ser'vesjmost effectively to secure the bar on the supports rigidly yet adjustably so thatthe supports may-he spaccd apart according to the re- 1-1;

' prises two circular plates30- and 31, the latach attaching means-e12, as shown, comter channeledas at 32 to receive the leg 24 of the support and provided with a border of crown-teeth 33 to mesh with teeth 34 borderingthe plate 30 -and disposed with their crownsin the plane of 'the'outer face of supporting leg 24. These'ftwo plates, are. centrally secured together and to the=leg24 by a bolt 34, and are further secured to-" get-her and-to the car-frame by a tu-clip 35. The down-bending horn of frame A (common in many makes of cars) is of channeled ,form in' cross section providing i nteriorl y an arciiate edge a. and on the outer face; of

positiomofsaid plate'to accommodate such 'rightv-and-left attachment necessitates" that the U-bolt 35 which embraces the frame and engages ,the plates shall take different'positions relative tothe plates, wherefore I;

form in each plate two pairs of-bolt receiving openings 38,- 38 and 39, "39' symmetrica-llyn disposedwith respect to the crest of the arc of lips 36 on plate 30. Each of these holes I preferably elongate on an arc to give some leeway for adjustment of the-,position of supports 11 with respect' to the earf fra me or to the plate 30 rib-positioned on the The firm andndeq ate attachment of support 11 to frame A th 's provided develops. substantially: the full-' stren gth of "the supports and insures that shocks to the ihar still not displace the-fastened ends offlthe late 30 I provide lips36 including there- Between a groove 37'to receive such edgea.

attaching" said supporting means -to a carframe comprising a air of plates positioned at opposite sides 0 the supporting means,

one receivin the supporting means, and the other plate av'ing projections for. engage mentwvith thecar frame,'said plates having interlocking teeth and registering openings and means engaging said openings for securing 'the plates to a car frame. I I
